11) all, whom t may concern.-

Be it known that I, JAooB TAMAS W1LLIs, a citizen of the United States, residing at Macon, in the county of Bibb and State of Geor ia, have invented certain new and useful Improvements in Pipe-Couplings, of which the following is a specification.

My invention relates to improvements in hose or pipe couplings, particularly for use with what are generally known as anglecocks of train-pipes.

It hasfor its object to provide for readily or quickly effecting the coupling operation as well as the uncoupling operation and to carry out the same in a simple, economic and efiective manner.

Said invention consists of certain structural features substantiall as hereinafter fully disclosed and pointe out by the appended claims.

In the accompanying drawing illustrating the preferred embodiment of my invention- Figure 1 is a broken partly sectional and partly side elevation thereof. Fig.2 is a full side elevation, and Fig. 3 is a front elevation of the same.

In carrying out my invention, I provide the angle-cock casting or member 1 of the train-p e, referably with an internally screw-t ea ed nozzle or arm 1; and into this nozzle is screwed, or otherwise connectedthereto, a tubular couplin -member or section 2, as at 2", while with the conti uous end of the train-pipe or hose is suitab y secured the other coupling memberorsection 3, the two members having seated in the meeting enlarged ortions or faces thereof packing rings or a utments 4 for forming a steam or air tight joint at that point.

The coupling member or section 2 has a lateral hook-terminated or ended stud 2 curved or ointed outward and beyond the face of said member; and oppositely to said stud said cou ling member has two outstanding space -apart lugs 2 between which Specification of Letters Patent.

is pivoted or hung a T-sha ed gravity link 5, the purpose of which wil be presently apparent.

The coupling-member or section 3 has a lateral eye-equipped stud 3 to receive the hook-ended stud 2 of the coupling-member 2 so as to interlock therewith as shown in efiecting the coupling operation. This same coupling member 3 has op ositely to the eyeequipped stud 3, paralle spaced-apart lugs 3 having outward tapered ends or terminals, and which are also flared inward, whereby, it will be noted, that, as the link'5 is inserted therebetween and that as its cross-head is forced into engagement with said lugs, along the inward flared lower surfaces of said lugs, a binding or wedging action will result be-v tween said cross-head and said parallel lugs 3 thus effectively coupling the members 2 and 3 to ether.

It is o vious that the coupling-member 2 could be readily cast integral with the arm 1' of the angle-cock casting 1 without materially changing the aforesaid results.

I claim:

A pipe-coupling comprising two members or pipe-sections, one having an arm-extension beyond its face curving or hooked downward and op osite of this latter a ravity T-shaped link, and the other mem er or pipe-section provided with an eye-ended lug to receive said hook-ended arm-extension and opposite said lug with a bifurcated or slotte lughaving an underneath beveled surface, said T-form of link entering the slot of the latter lug and having its head engaging the beveled surface of said lug.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

J AOOB TAMAS WILLIS.
